  class Recipe
    def construct_chroot ... end
    def deconstruct_chroot  ...  end
    def compile
      construct_chroot()
      real_compile
      deconstruct_chroot()
    end
  end

  class SpecialRecipe < Recipe
    def real_compile
      ... # special compile code
    end
  end

Just a simple template design pattern. The only catch is that you can't
put the special compile code in a method called compile. (I mentioned
before that the kind of wrapping you use here can be done using
subroutines, but wrapping allows it to do in-place, remember that?)

I'm busy catching up now with reading/understanding the wrapping stuff. I
still need to find that example for cflow, but that's for tomorrow when I
pickup the notes (if I don't forget). When I find something interesting,
I'll let you know.
